This invention relates to certain novel improvements in combination tools and more particularly to a combined journal gage and caliper and is an improvement over such a I tool as disclosed in my co-pending application, Ser. No. 159,201, filed in the Patent Ofiice on or about Jan. 5, 1927. i

The salient object of my invention is to provide a tool of the above described character which will be simple and economical in manufacture and efficient in use.

Another object of my invention is to provide a device which will embody numerous advantages over the device disclosed in my co-pending application and one of the major features resulting from the improvements is that I provide in this device a member movable transversely of the rule member which will be arranged such that it will facilitate the measurement of a worn journal.

When railroad car wheels and axles are changed under cars of ownership foreign to the companying making these changes a wheel and axle statement must be furnished the car owner as` required by the code of rules M. C. B. governing the condition of and repairs to freight and passenger cars for the interchange of traflic adopted by the American Railway Association-Mechanical Division. The information, or rather the data that must be'shown on this statement includes, among other things, the actual journal length dimension, the actual journal diameter dimension, the actual wheel seat diameter dimension, and the actual axle center diameter dimension. The actual journal length dimension isat present procured by the usage of an ordinary rule of sufficient length with proper graduations. This rule is laid upon the j ournal and the dimensions are taken therefrom by direct reading. This method of procuring dimensions is unsatisfactory due to the difficulty encountered in positioning the rule at the proper point at the back end of the journal and difficulty is also encountered in making the necessary allowance for journal collars worn unevenly. The journal diameter dimension, wheel seat and axle center diameters are at present procured by the employment of an ordinary caliper. These dimen- 1927. Serial No. 195,086.

sions are likewise procured in an inadequate manner and inasmuch as it is essential to procure positive accurate dimensions it is the object of this invention to provide a combination tool which may be employed to obtain these dimensions which will give instantaneous and accurate dimension readings.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of parts to be here- L'. inafter described and claimed.

The invention will be best understood by reference to the accompanying drawings, showing the preferred form of construction and in which:

Fig. 1 is a side elevational view of a preferred embodiment of my improved tool mounted in operating position;

Fig. 2 is a plan view of the device;

Fig. 3 is a sectional detail view taken on the line 3--8 of Fig. 1; and

Fig. 4 is a side elevational view of the rule in folded position.

In the following description my improved rule is described as being collapsible in order l to facilitate carrying thereof. However, it is to be understood that if this rule is used in shops for bench work wherein the tool need not be transported any great distance, the tool may be constructed of a single piece. Inasmuch as the inspectors, who will be chief users of this device, usually travel from point to point I have found that a collapsible form is highly suitable to their needs since it affords easy carrying of the tool.

The preferred construction of my invention consists of providing two sections 10 and 11 that are pivotally attached together as at in order that they shall be foldable upon cach other to facilitate transportation thereof. rEhe sections 10 and 11 have a system of graduations provided thereon along one edge, these graduations being arranged so as to read continuously. It is preferable that these =fgraduations be in inches and be calibrated so that measurements may be taken down to g1g of an inch without interpolation.

The section 10 embodies a projection 13 along the edge on which the graduations are provided and said proj ection embodies a side which extends at right angles to the edge of said section 10. The projection 13 is made of a width suitable for procuring proper dimension that will be in accord with the requirements of the mechanical division of the American Railway Association. The dimensions required are at the present time procured in accordance with the instructions shown on circular' No. D. V. 452, that is published by this organization. In the present instance, in preferred forms, the edge oi the projection 13 opposite the straight perpendicular edge embodies a portion that is paralllel with this perpendicular edge for a short distance and then an arc is struck so to connect these two edges. The edge is arranged so that when this edge is contacted with the side of a worn ournal, proper dimensions will be obtained. It is readily apparent that if the association changes the instructions for taking these dimensions that this arrangement would be varied in accordance with vthe changes in order that proper dimensions might be obtained.

In order to obtain the dimension of the journal length after the projection 13 has been contacted with one edge of the journal, a sliding member 14 is provided on the section 11. A slot 15 lis provided in `this section and a headed pin 16 extends through this slot so as lto slidably `secure the `member 14 to the section 11. Mounted for sliding movement through the member 14 is .a gage member 17 that embodies an arrangement such as at 1S on jthe upper `end lthereof so as to limit the downward movement of the Vstop member 17. The gage lmember 17 embodies an edge which extends at right angles tothe section 11 and at the lower end on the side opposite from this edge the `gage member 17 embodies a projection such as 18. This sec- ;tion 18 is of a contour that will permit rthe member 17 -to properly engage `the wall of the journal in order that a dimension in accordance ywith the heretofore described circular may be obtained. rlfhe contour of this member may also be changed in the `event that the associationchan ges `the requirements on dimensions. In the device or' my co-.pcnding application this gage member 17 was not provided and this member represents a particular vimprovement over that device since Ait permits a more accurate method for obtaining proper journal length dimension and the manner in which this accomplished is setI torth more clearly hereinafter.

Referring to Fig. 1, vthe manner in which this tool is used may be seen. The Jformed portion of the projection 13 is contacted with one edge of the journal and then the member 14 is moved `along the section 11 until the projection 18 envagesthe other wall of the journal. The point 18 of the projection 18 will then be aligned with a graduation on the section 11 which will indicate the length of the journal.

The section 10 embodies a projection 19 that engages a shoulder on the section 11 so as to limit the opening movement of said sections and to properly align them.

Pivotally connected to the member 14 is an arm 20 that is adapted to vserve yas one leg of a caliper. An arrangement is provided on the member 14 such that when the arm 20 is moved downwardly into operating position it willlimitthe movement of said arm andproperly position it. A sliding member 21 is provided on-the section 10 and pivotally attached thereto as at 22 is an arm 28 that is adapted to serve as the 4other leg of the caliper. The arms 20 'and 23 embody formed projections 24 and 25 on their lower ends for purposes well'understood in the art.

In using the calipers to obtain journal wheel seat and axle center dimensions, one of the sliding members carrying the legs that yContact these calipers is fixed 4in respect to the graduations on the section carrying this sliding member. This liXed leg is then con tacted with one side .of the part to be `measured and then the other Ileg is Vbrought into Acontact with the other side of .the member such as 267 27 and 28, thepurpose and manner Vofuse of which will be readily apparent `to :any one skilled -i-n the art.

In order that the .tool `may'beused'for `gag- -ing journal collars, I provide recesses such as 29 and 30 lin the sections 10 and 11, of predetermined sizes in order that'the .magnitude of these flanges may be determined.

From the foregoing, it is apparent that I have provided a combination tool which may vbe employed to obtain dimensions yon journals of the heretofore described type, said tool being arranged so that only Vproper dimensions may be obtained. In this manner, I eliminate a great wasteand efliectilarge economy by preventing the scrapping ofiserviceable axles `due to the fact that incorrect dimensions have been'secured. Y

In addition to the foregoing, I have :provided a combination tool which maybe expeditiously employed to obtain the required dimensions.

In addition to the foregoing I have provided a tool which may be-employed to obtain all the dimensions in a very rapid manner and thus I effect a considerable saving of time.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modiications as come within the scope of the ap pended claims.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent is z 1. In a combination tool', two rule members pivotly connected together for folding upon themselves, means for limiting the pivotal movement of the rule members for positioning the rule members in substantial alignment with respect to each other, said rule members having slots formed therein, carriage plates disposed on one side of each of said rule members but on opposite sides thereof, caliper legs, means extended through said slots and secured to said carriage plates for securing said Caliper legs for disposition opposite said carriage plates and for pivotal movement with respect to said rule members, one of said carriage plates having a transverse slot extending therethrough, a gauge member in said slot having an enlarged head at one end thereof, said gauge member having a portion extending at rightangles to the extent thereof at the end opposite said enlarged head.

2. In a combination tool, two rule members pivotly connected together for folding upon themselves, means for limiting pivotal movement of the rule members for positioning said rule members in substantial alignment with each other, said rule members having slots formed therein, carriage plates disposed on one side of each of said rule members but on opposite sides thereof and slidable relative to said rule members, caliper legs, means extended through said slots and into said carriage plates for connecting said caliper plates to said carriage plates on the sides-of said rule members opposite said carriage plates, one of said carriage plates having a slot extending transversely therethrough, a flat relatively elongated gauge member having an enlarged head at one end thereof having a tapered side, and a foot portion at the opposite end of said gauge member extending at rightangles to the main extent thereof.

In testimony whereof I aiiix my signature.
